About Genticel

Genticel's versatile platform, Vaxiclase, is well suited for the development of various immunotherapies. A partnership on the use of Vaxiclase as an antigen per se (GTL003) has been established with Serum Institute of India Pvt. Ltd. (Serum Institute), the largest producer of vaccine dose worldwide. This agreement covers territories in emerging markets only, and could generate up to $57 million in revenues for Genticel, before royalties on sales. It will enable Serum Institute to develop acellular multivalent combination vaccines against a variety of infectious diseases, including whooping cough. In November 2016, the last preclinical milestone was reached, opening the path to formal preclinical testing prior to clinical development and subsequent commercialization.

On December 22nd 2016, Genticel signed a contribution agreement with the shareholders of Genkyotex pursuant to which, subject to the approval of Genticel's shareholders at a meeting expected to be held in the first quarter of 2017, Genkyotex's shareholders will contribute in kind 100% of the Genkyotex share capital (on a fully diluted basis) to Genticel, which will issue new shares in remuneration for the contribution. Upon completion of the proposed transaction, Genkyotex's shareholders will hold 80% of Genticel's share capital & voting rights (on a non-diluted basis).

Genkyotex is developing a portfolio of NADPH oxidase (NOX) oral small molecule inhibitors, which have therapeutic potential for the treatment of multiple significant clinical indications with substantial unmet need, including fibrosis, inflammatory pain, angiogenesis, cancer growth, and neurodegeneration. Genkyotex is currently developing two clinical stage, first-in-class NOX inhibitors and is conducting research on several other pre-clinical molecules.
